ICSH 2025 Morphology Symposium attendees

The ICSH 2025 Morphology Symposium, organised by the ICSH in collaboration with the University of Western Australia, was held in Perth from 24th to 26th November 2025. The event gathered more than 130 participants from across the Indian Ocean region, including invited speakers and distinguished guests. This year, 11 recipients were awarded for the ICSH Educational Grant. Unfortunately, two were unable to attend as they could not get a visa to enter Australia. The awardees represented institutions from Zambia, Fiji, Indonesia, Cambodia, Malawi, Tanzania, Namibia, and myself from Malaysia.


ICSH extends its heartfelt thanks to “Siemens Healthineers, Sysmex, URIT, Business Events Perth, and Cancer Council Western Australia for their generosity and sponsorship, as well as to the University of Western Australia for the warm hospitality including the excellent plenary and breakout venues, the delicious meals, and the comfortable accommodation provided at St George’s College.


Each participant received a symposium pack bag, complete with the programme book and, most valuably, the 230-page Morphology Course Notes. This treasured resource will undoubtedly be placed at the multi-headed microscopes during slide reviews in my institutions, allowing other haematology students and colleagues to benefit from the knowledge shared.


The scientific programme opened with three plenary lectures by Professor Wendy Erber, who provided comprehensive updates on ICSH standards and bone marrow reporting, building on the 2008 guidelines. The following day, Professor Anna Schuh delivered an excellent plenary on CLL and liquid biopsy, highlighting its faster turnaround compared with conventional histopathology, followed by Dr Ben Hedley, who presented on standardising flow cytometry for leukaemia diagnosis and monitoring using CLSI guidance.


A major highlight of the symposium was the series of morphology sessions structured from red blood cells to white blood cells, and concluding with lymphoid disorders and metastatic infiltration delivered by Dr Matthew Wright, Prof Wendy Erber, Dr Jason So, and Dr Katharine Lowndes. And this was followed by the Morphology Quiz, which I had the honour of conducting using Kahoot. There were noise, excitement and joyful chaos, thanks to the delightful diversity of answers! Congratulations to Dr Lai Ngan Shan, the winner of the Quiz. Each session was captivating, insightful, and filled with memorable teaching moments, including a charming new term introduced during the plasma cell discussion: “Amphophilia!” describing their affinity for both haematoxylin and eosin.


The afternoon breakout sessions were equally enriching, offering a mixture of Meet-the-Expert discussions, free paper presentations, which provided excellent opportunities especially for non-native English speakers to build confidence. Many challenging and fascinating cases were showcased, offering important learning points, particularly from resource-limited settings where diagnostic constraints influence outcomes. After all, morphology remains the fundamental starting point in haematological diagnosis.


The intimate morphology revision sessions with Prof Erber were among the most sought-after activities, and I was fortunate to secure a place on Day 1. Other participants also greatly enjoyed the always fully booked PathWest (QEII) laboratory visit, expertly guided by Tracy Dixon, including personalised slide reviews that reinforced the learning from the morning sessions.


My sincere appreciation goes to the organising committee, the distinguished faculty, all presenters, and every participant who contributed to the great success of the ICSH 2025 Morphology Symposium.

This symposium was truly phenomenal. What did I learn from it? Honestly: everything!: expanded morphology knowledge, enriched perspectives, meaningful networking with fellow morphologists and reunion with dear colleagues. Above all, I was reminded that despite our different languages, countries, ethnicities, and professional backgrounds, we all share the same universal language of morphology a vocabulary that unites and inspires us.


Allow me to express my sincere gratitude to the ICSH for awarding me the Educational Grant. I am truly grateful for this support.


With that, wishing everyone a wonderful year ahead and looking forward to many more inspiring ICSH events to come. Happy New Year!


Thank you so very much. Till then,


Best wishes,

The ICSH held the 2025 General Assembly at the Royal Sonesta Hotel in Chicago on 29th and 30th September and attended by over 50 members and invited guests. ICSH sincerely thanks Sysmex America for their generous support in hosting the meeting and the generous hospitality provided.


During the Assembly all ICSH members (i.e. Corporate and Affiliate members and the Management Board) learned of the ICSH activities over the past year, programmes of work that are underway and plans for the coming year. It was evident that there is growing global interest in the ICSH and its activities as evidenced by the number of people accessing the website, new members (Corporate and Affiliate), interest in contributing to Working Group projects and the number of applications for ICSH Scholarships. Because of this growth, the Board will be increasing the membership to a maximum of 12; a call will soon be made for expressions from scientists and / or haematologists interested in joining the ICSH Board. 


Over the past 12-months the ICSH has completed a number of projects leading to publications, all of which are freely available and accessible via the ICSH website. These include: 


  • Clinical applications of bone marrow CD34 immunohistochemistry assay 

  • Guidance for internal quality control policy for blood cell counters 

  • ICSH/JSLH reference measurement procedures for enumeration of erythrocytes and leukocytes 

  • ICSH immunodifferential reference method for white blood cell enumeration and differential by flow cytometry 

  • ICSH guidance on the validation of laboratory developed tests in haemostasis 

  • Update on standardization of HbA2 and HbF (work together with IFCC)


Presentations were given by Working Group leads on projects underway, including: monocytes nomenclature, bone marrow examination and reporting, blood viscosity, malaria diagnostics, measurement of uncertainty, monitoring of direct thrombin inhibitors and measurement of non-clotting factor options for haemophilia. Proposals for new projects were discussed and are under consideration by the ICSH. 


A highlight of the Assembly was a special session devoted to the evolving role of artificial intelligence in haematology. There were three highly informative presentations given by Drs Stephen Master, Samer Albahra and Wolfgang Kern, followed by a dynamic panel discussion. Topics included guidance on manufacturer-developed and in-house AI algorithms, minimum performance metrics, operability, and quality assurance, all issues considered directly relevant to the ICSH. The Board will now consider whether, how, and when to develop related materials on artificial intelligence.


Dr Katharine Lowndes gave an overview of the upcoming 3-day ICSH Morphology Symposium (Perth, Western Australia, 24-26 November).  There has been enormous interest in this new ICSH educational initiative. Registrations were closed 3 months prior to the event as all places had been taken. The ICSH is supporting the attendance of scientists and haematologists from resource-constrained countries (including Tanzania; Cambodia; Fiji; Indonesia; Zambia). The programme includes live microscopy presentations, personal morphology review, plenary lectures, oral presentations and meet-the-expert sessions. The ICSH thanks the Organising Committee for their time and effort in preparing what should be an excellent event which promises to be an ICSH highlight for 2025. Already the ICSH is being asked about when and where the next Morphology Symposium will be held!


The General Assembly received updates on many of the projects currently underway, including blood viscosity, guidance for malaria testing, standardization of monocyte morphology, platelet clumping,  and revisions to the 2008 bone marrow guidance document. In haemostasis updates were given on measurement of uncertainty, acquired haemophilia A, laboratory measurement of emicizumab and other non-replacement therapies for Haemophilia and PT / APTT measurement. Proposals for new projects were discussed and are under consideration by the ICSH.


ICSH Affiliate members gave updates to the General Assembly of their activities and we discussed relationships with the WHO and JCTLM.


The winners of the ICSH Scholarships were announced:


Sam Machin Scholarship (supported by Mindray) 

Dr Aditya Tedjaseputra (UK): “Standardisation and validation of fms-like tyrosine kinase 3 internal tandem duplication (FLT3-ITD) measurable residual disease (MRD) by ultra-sensitive next generation sequencing (NGS)” 


Carol Briggs-Smalley Award (supported by Sysmex America Inc.) 

Zo Ee Wong (Australia): “Evaluation of CAR T cell quantification methods for monitoring therapy success”


The Assembly noted with sadness the recent passing of Drs Alexander Kratz and Bruce Davis, both eminent haematologists and former ICSH Board members who had given their time generously to the ICSH and the profession. 


Thanks to all participants and presenters who made the General Assembly a success. We look forward to a constructive year ahead and hearing more updates at the 2026 General Assembly in Shanghai. If you would like further information about the General Assembly, please contact the ICSH through the website or via email (admin@icsh.org). I extend my sincere thanks to Sysmex America, and especially Andy Hay and April Strong, for their generous support in hosting the General Assembly in Chicago.
